What term describes the use of a controlled substance medication for recreational purposes?

The term that accurately describes the use of a controlled substance medication for recreational purposes is "abuse." Abuse involves taking medication in a manner other than prescribed or intended, often for the euphoric effects that such substances can produce. This behavior is a considerable concern in pharmacology and public health, as it can lead to addiction, overdose, and various health complications.

Although "diversion" could also seem relevant, it specifically pertains to the unlawful transfer or distribution of controlled substances from legal to illegal channels. It usually means that the medication is being redirected from its intended medical use to illicit use, but does not exclusively describe the act of use itself. Understanding these distinctions is crucial since effective strategies for prevention and intervention can only be implemented when the terminology is used accurately.
